Official basis (Method): AWPA ratified copper-indicator text supports these reagents for copper. They must not be described as boron stains; use the controlled AWPA method and treatment-specific acceptance requirements.

Procurement note: Ratified AWPA text names these components. Copper indicators are alternatives, not boron stains; confirm final current method and preservative compatibility.

Guideline-backed stain reporting for every laboratory.

Privacy, terms & disclaimers
Privacy

Patient data entered in demo pages stays in your browser and is never stored. Data saved in the signed-in workspace is kept in your laboratory's secured database, visible only to approved staff of that hospital by role; researchers see anonymised records only. The microphone is never on in the background: a box mic switches on only when you tap it, shows a red 'Listening' badge and turns itself off within 12 seconds; hands-free Voice Commands stay on only while their red switch is on and turn off after 30 seconds of silence. Speech is converted to text by your phone or browser's speech service; for signed-in staff, when that is unclear, the short clip for that one box is sent to an AI speech model to be understood and is not stored by STAINIC. Microscope photos sent for AI suggestions must show only the smear, never patient identifiers. We do not sell or share personal data.

Terms of Use

STAINIC is provided to authorised laboratory professionals. You are responsible for the accuracy of entries - including anything filled by voice, OCR or AI - for keeping your login private, for sharing report links and PINs only with the patient or treating doctor, and for complying with your institution's policies and local health-data laws. Access may be revoked for misuse.

Medical & Educational Disclaimer

Guideline content, scores, pattern hints, auto-drafted impressions and AI suggestions from voice or microscope photos are decision-support and educational aids. They can be wrong and do not replace the professional judgement of a qualified pathologist or microbiologist, who must review and sign every report.

No Treatment Advice

STAINIC is a laboratory reporting tool, not a treatment website. It does not diagnose, prescribe or recommend therapy to patients. Patients should discuss results with their treating doctor.

Legal

Stain grading follows published standards (CLSI, WHO, NTEP, ICSH, Bethesda, CAP) and remains the property of their authors. OCR is approximate and must be checked. Provided "as is" without warranty; liability is limited to the extent permitted by law.
